Class 8 doors are now Doors with a Swing, from docs/engine/doors.md "Class 8".

• Template fields: ease +0x18, waits from flags 0x10000000 (16, shut) and 0x20000000 (8, open), trigger radius +0x34, damage +0x32. The first target is the open end.
• Running: they think only while the player is within the radius (2D from the placement), matching the enter/leave scheduling.
• Each think:
  • A wait counts down by 136.
  • Then the speed is set to 256 + ease x rsin(((angle - shut) << 11) / (open - shut)) / 4096, and the hinged step and stop apply.
  • At an end the target flips, and the door waits 4096 if its flags name that end.
• Blocked: Damage +0x6d to the player at most every 25 frames (51 VSyncs), but not in the hub. Level 3's 159/160/595/602 hurt 15.
• No Triangle use.

Checked by watching DB6 (990/991) and DB3 (159/160/595/602) swing open and shut while standing near; no panics in levels 2, 3, 6.
